Removing T'Blade Holders

[Speed Demon 0]

I gave my G35s with T'Blades on them to my LHS and they said they don't have the wrench they need to remove them. Apparently it is some sort of "Allen" wrench. Is this the wrench that I need?

A small flathead should work.

Or a hex bit.

you can buy it online at thepenaltybox.com or various other websites, or you can use a small allen key. Get one of those sets with a bunch of head sizes on them, and use that
